Summary:Electrochemical impedance spectroscopy technique was used to describe behavior of AB sub(5)-type hydrogen storage alloy. Impedance investigations were performed during cyclic voltammetry measurement and charge/discharge cycles. The comprehensive interpretation of instantaneous impedance spectra obtained in potentiostatic mode allowed further to interpret impedance results in galvanostatic mode. Proposed methodology enabled to trace electrical parameters as a function of state of charge (SOC) and depth of discharge (DOD).
